[0033] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a magnetic connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three or more, etc., unless otherwise clearly specified and limited.
[0035] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0036] In order to solve the problems existing in the prior art, an embodiment of the present application provides a buffer receiving device for rejecting cigarette strips.
[0037] like Figure 1As shown, a buffer receiving device for rejecting cigarettes comprises a guide assembly 1, a buffer assembly 2 and a collection box 3; the guide assembly 1 is used to adjust the state of the cigarettes falling onto the buffer assembly 2, ensuring that the cigarettes are roughly perpendicular to the extension direction of the buffer belt 21 when they fall; the buffer assembly 2 is used to buffer the cigarettes and transport the buffered cigarettes to the collection box 3, and comprises a buffer belt 21 and a retraction reel 22; the buffer belt 21 is arranged below the guide assembly 1, with an extension direction perpendicular to the cigarette falling line, for receiving the cigarettes, and is fixed on one side, such as plug-in fixation or snap-on connection, To facilitate disassembly and assembly, the other side is rolled up on the retraction reel 22; the retraction reel 22 is fixedly arranged, and can release the part of the buffer belt 21 rolled up on the retraction reel 22 when the cigarette falls onto the receiving state on the buffer belt 21, and roll up the buffer belt 21 when it is in the non-receiving state; the top of the collection box 3 is open, and is used to receive the cigarettes dropped by the buffer component 2, that is, after the cigarettes are adjusted by the guide component 1, the length direction is consistent with the moving direction, and is perpendicular to the extension direction of the buffer belt 21. When the cigarettes fall onto the buffer belt 21, they continue to move due to inertia until they are separated from the buffer belt 21, and then fall into the collection box 3.
[0038] The present invention provides a buffer receiving device for rejecting cigarettes. The device adjusts the falling cigarettes with a guide component 1 so that the length direction thereof is roughly consistent with the width direction of a buffer belt 21. The adjusted cigarettes are then buffered by a buffer component 2 and transported to a collection box 3. The buffer component 2 buffers the cigarettes, which can reduce the speed of the cigarettes entering the collection box 3, thereby reducing quality problems caused by collisions of the cigarettes. The buffer belt 21 and the retraction reel 22 cooperate to perform buffering, which not only buffers the cigarettes, but also reduces the distance the cigarettes are transported to the collection box 3 because the buffer belt 21 is pulled out during the buffering process, further reducing the collision force between the cigarettes and the collection box 3. The falling speed of the cigarettes is reduced by more than 60%, the damage rate of the cigarette packaging is reduced to below 0.05%, and the noise is low.
[0039] In some preferred embodiments, Figure 2 As shown, the retraction reel 22 includes a fixed shaft 221, a reel 222 and a torsion spring 223; the fixed shaft 221 is fixedly set; the reel 222 is sleeved and rotatably connected to the fixed shaft 221, for winding up the buffer belt 21; the torsion spring 223 is sleeved on the fixed shaft 221, and is connected to the fixed shaft 221 and the reel 222.
[0040] In some preferred embodiments, the retraction reel 22 is inclined toward the discharge side; thereby, on the one hand, it facilitates the output of cigarettes, and on the other hand, it further reduces the distance that the cigarettes fall to the collection box 3, thereby reducing the impact force; preferably, the inclination angle is 45°, which ensures sufficient buffering effect and reduces the distance that the cigarettes fall to the collection box 3; further preferably, the buffer belt 21 is made of a flexible material. Based on this, in conjunction with the setting of the retraction reel 22 being inclined toward the discharge side, in the natural state of the retraction reel 22, the non-wound part of the buffer belt 21 naturally droops to form a roughly V-shaped guide groove, which can further guide the fallen cigarettes, and thus the output position is more fixed, and in conjunction with setting a buffer structure on the surface of the collection box 3 at the output position, the impact force is further reduced, thereby reducing quality problems caused by collisions.
[0041] In some preferred embodiments, Figure 3 As shown, the retraction reel 22 also includes a mounting bracket 224; the mounting bracket 224 is fixed to the collection box 3; the fixed shaft 221 is installed on the mounting bracket 224; specifically, the mounting bracket 224 can be a gantry structure, and both ends of the fixed shaft 221 are fixedly connected to the mounting bracket 224, and the fixed shaft 221 is installed and fixed by the mounting bracket 224, such as fixing the mounting bracket 224 to the inner wall of the collection box 3.
[0042] In some preferred embodiments, Figure 4 As shown, the retraction reel 22 includes multiple reels 222 and multiple torsion springs 223; the reels 222 and the torsion springs 223 correspond to each other one by one, and are all rotatably sleeved on the fixed shaft 221, and the multiple reels 222 jointly roll up the buffer belt 21; based on the setting of multiple reels 222 and torsion springs 223, the multiple reels 222 jointly roll up the buffer belt 21, based on this, when the cigarette falls onto the buffer belt 21, the buffer belt 21 impacted by the cigarette is pulled out, and the other parts can remain unchanged, which can avoid the twisting movement caused by uneven force on the buffer belt 21 and affect the normal rotation of the retraction reel 22, such as the retraction reel 22 getting stuck, affecting the buffering effect.
[0043] Preferably, the buffer belt 21 is made of a flexible material, and the retracted reel 22 is inclined toward the discharge side; based on this, when the cigarette falls, the buffer belt 21 at the falling position is pulled out more, that is, the reel 222 in this part is subjected to a large force, and the reel 222 in the remaining part is subjected to a small force. Compared with the method of using one reel 222, the setting of multiple reels 222 can reduce the initial resistance when the cigarette falls, that is, the initial impact between the buffer belt 21 is smaller, which can improve the buffering effect, and under the same impact force, the setting of multiple reels 222 allows the buffer belt 21 to be pulled out more When the cigarette falls closer to the discharge side of the buffer belt 21, the distance the cigarette falls to the collection box 3 can be further reduced, and the collision force can be reduced. When the cigarette falls away from the discharge side of the buffer belt 21, the buffer belt 21 is stretched to the maximum and then reset to a natural state (the torsion spring 223 of the retraction reel 22 is in a non-deformed state). At this time, the speed of the cigarette is approximately zero, and the retraction reel 22 is tilted toward the discharge side, that is, in a natural state. The cigarette slides down naturally under the action of gravity. At this time, the buffering effect is the greatest, and the collision force with the collection box 3 can also be reduced, thereby improving the product quality during the rejection process.
[0044] Preferably, the torsional force of the multiple torsion springs 223 increases sequentially from one side of the cigarette discharging to the other side; based on this, the deformation on the discharging side becomes larger, and the deformation on the other side becomes smaller, and the cigarette is tilted more, which is convenient for discharging, especially when the falling position is close to the discharging side of the buffer zone 21, the buffering effect can be improved, and based on the greater inclination of the cigarette, its direct collision with the side wall of the collection box 3 can be reduced, further reducing the collision force.
[0045] Preferably, if Figure 5 As shown, the other end of the buffer belt 21 is rotatably installed through a connecting component 23, and the connecting component 23 includes a rigid connector 231 and a flexible connecting rope 232; the rigid connector 231 is arranged along the width direction of the buffer belt 21 and is fixedly connected to the buffer belt 21; the flexible connecting ropes 232 are arranged in pairs, one end of one of them is connected to one end of the rigid connector 231, and one end of the other is connected to the other end of the rigid connector 231, and the other end of the flexible connecting rope 232 is fixedly arranged; based on this, when the cigarette falls onto the buffer belt 21, it has a horizontal forward and a vertical downward component speed, wherein the buffer belt 21 is driven to shake under the horizontal component speed, and the component speed in this direction is buffered and decelerated to avoid the component speed in this direction being too large and the cigarette directly sliding out of the buffer belt 21 and colliding with the collection box 3.
[0046] Further preferably, the elasticity of the paired flexible connecting ropes 232 close to the discharge side of the buffer belt 21 is greater than that of the other side; at this time, combined with the solution of tilting the retraction reel 22 toward the discharge side, the inclination angle of the cigarette strips can be increased, reducing the risk of direct collision between the cigarette strips and the side wall of the collection box 3.
[0047] Further preferably, multiple torsion springs 223 are arranged at intervals so as to be able to move elastically along the fixed shaft 221, thereby improving the adaptability to uneven pulling of the buffer belt 21, that is, when the buffer belt 21 not only moves along the rotation direction of the reel 222, but also moves axially along the fixed shaft 221, the reel 222 can move accordingly to ensure the buffering effect.
[0048] In some preferred embodiments, Figure 6 As shown, the buffer belt 21 includes a flexible layer 211 and a fluff layer 212; the fluff layer 212 is arranged on the top surface of the flexible layer 211; based on this, the cigarette is buffered by the fluff layer 212, and the friction between the cigarette and the cigarette is increased to prevent it from sliding out directly, and the horizontal component speed is buffered and slowed down; the fluff layer 212 can be cotton fluff or fluff of other materials, and the specific density of the setting can be determined according to the working conditions, and it can meet the requirements of buffering and gravity discharging.
[0049] Preferably, the flexible layer 211 is a canvas belt.
[0050] In some preferred embodiments, Figure 1 As shown, the guide assembly 1 includes a first guide member 11 and a second guide member 12; the first guide member 11 and the second guide member 12 are spaced apart on both sides of the cigarette falling line, and the opposite surfaces are inclined surfaces to form a guide channel with a larger top and a smaller bottom, that is, the cross-section of the guide channel is an inverted trapezoidal guide channel, and the buffer belt 21 is arranged at the bottom outlet of the guide channel, such as a size larger than the bottom outlet of the guide channel; its width is preferably smaller than the adjusted length.
[0051] In some preferred embodiments, the first guide member 11 and the second guide member 12 are both strip-shaped structures with a right-angled trapezoidal cross-section perpendicular to the extension direction, and the two are arranged in parallel.
[0052] In some preferred embodiments, the bottom of the guide assembly 1 and the buffer assembly 2 are located in the top opening of the collection box 3, and the top of the guide assembly 1 protrudes from the top opening of the collection box 3; thereby, the cigarettes are prevented from sliding directly out of the buffer belt 21, and the collection box 3 can collect all cigarettes.
[0053] In some preferred embodiments, Figure 1 As shown in the figure, the surface of the collection box 3 facing the buffer zone 21 is the buffer side surface 31; the buffer side surface 31 is used to flexibly buffer the fallen cigarettes; based on the setting of the buffer side surface 31, the force of the collision between the cigarettes and the side wall of the collection box 3 is further reduced.
[0054] Preferably, the buffer side 31 includes a sponge board 311 and a flannel 312; the sponge board 311 is arranged facing the buffer belt 21 and blocks the cigarette falling path; the flannel 312 is covered on the surface of the sponge board 311 facing the buffer belt 21; the sponge board 311 provides horizontal buffering, and the flannel 312 provides downward buffering to avoid excessive collision with the bottom surface when sliding down from the side wall to the bottom surface of the collection box 3, causing serious bumps.
[0055] Further preferably, the flannel 312 is larger than the covered part of the sponge board 311, and the edge of the flannel 312 is connected to the sponge board 311; that is, the flannel 312 is in a wrinkled state. Based on this, during the sliding process, it is not only subject to the friction resistance of the flannel 312, but also directly blocked by the wrinkles, thereby improving the sliding cushioning effect.
[0056] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are protected by the present invention.
